What is the chemical name of arsenic?
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid.
Is arsenic the same as arsenate?

How is arsenic used as a poison?
Arsenic poisoning, or arsenicosis, happens when a person takes in dangerous levels of arsenic. Arsenic is a natural semi-metallic chemical that is found all over the world in groundwater. Intake can result from swallowing, absorbing, or inhaling the chemical.
Why arsenic is used in medicine?
Arsenic trioxide is used in combination with tretinoin to treat acute promyelocytic leukemia (APL; a type of cancer in which there are too many immature blood cells in the blood and bone marrow) in certain people as a first treatment.
What’s arsenic used for?
Arsenic is used industrially as an alloying agent, as well as in the processing of glass, pigments, textiles, paper, metal adhesives, wood preservatives and ammunition. Arsenic is also used in the hide tanning process and, to a limited extent, in pesticides, feed additives and pharmaceuticals.
Why is arsenate a poison?
A small molecule that can easily get into cells, arsenic can cause cell injury and death by multiple mechanisms. Interference with cellular respiration explains the potent toxicity of arsenic. In addition, arsine gas may interact directly with red cell membranes.
What is arsenate and arsenite?
Arsenic exists in two oxidation states—arsenate, As(III), and arsenite, As(V)—both of which are anions (see also Chapter 8). Although both forms are toxic, arsenite is much more toxic and is also very soluble and mobile in water environments.

What is the valency of arsenic in arsenate?
The arsenic atom in arsenate has a valency of 5 and is also known as pentavalent arsenic or As (V) . Arsenate resembles phosphate in many respects, since arsenic and phosphorus occur in the same group (column) of the periodic table. Arsenates are moderate oxidizers, with an electrode potential of +0.56 V for reduction to arsenites .
What is the difference between arsenate and diarsenate?
Where two arsenate ions are required to balance the charge in a formula, it is called diarsenate for example trizinc diarsenate, Zn 3 (AsO 4) 2 . The word arsenate is derived from arsenic acid, H 3 AsO 4. This moderately strong acid converts to dihydrogen arsenate ( H
